SAD-IRON HEATER.

Specification of Letters Patent.

Patented Aug. 23, 1910.

To all whom it may concern:

Be it known that I, LAIRD J. J AoxsoN, a citizen of the United States,residing at I Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements in Sad-Iron Heaters, of which the following is a specification, reference beinghad therein to the accompanying drawing.

My invention consists of a device for heating sad irons, and has for itsobject to provide means for supporting the irons within a heat-retainingshell over a burner, so arranged that the holder may be intermittentlyrotated to bring each heated iron in register with an opening having aclosing door in the shell or casing, and having means for preventingreverse movement of the holder, thus presenting aheated iron each timethe holder is rotated and insuring against removal of a cold iron.

The invention consists of the construction shown in the drawings andhereinafter more fully described.

In the drawings: Figure 1 is a side view of the device in elevation, seton a burner. Fig. 2 is a vertical sectional View on the line II. II. ofFig. 1. Fig.3 is a detail view in side elevation of the rotatable ironholder. Fig. 4 is a horizontal sectional view on the line IV. IV. ofFig. 2. Fig 5 is an enlarged plan view of the central portion of thesupporting base.

The device consists of a flat base 2 adapted to be set on a burner 3 oron the top of any suitable heating device, having an open body portionand an upwardly extending coniform shell or casing 1 provided with anopening and closing door 5 hinged at 6.

The base 2 is conveniently made of three radially disposed arms leavingthe main intervening space open between the arms for circulation of thegases, one of said arms being widened out as at 2 immediately be ipw thedoor 5 to protect the hand from the eat.

Base 2 is provided at its central portion with an upwardly extendingbearing 7 hav ing ratchet-shaped locking teeth or abutments 8 and acentral hole, and said bearing supports the lower end of the rotatableiron holder by its pivotal stem 9 in said hole. The holder consists of abase 10 provided at its central under portion with a series of lockingabntments or ratchet teeth 11 adapted to engage teeth 8 and rotatablethereon in one direction only, and also hav ing a series of upwardlyextending inwardly sloping sad iron brackets 12. These brackets areshaped to receive the bottom face of the sad iron and have supportinglugs 13 whereby the iron is supported with its bottom facing the hollowinterior of the rotatable holder.

The brackets 12 are connected together at the top by an integral cappiece 12 having a stem 14 which extends through and forms a journalbearing in the top 15 of easing 4, the stem having a turning handle 16.

In operation, the entire device is set on top of the burner, the heat ofwhich passes upwardly within and is confined by the casing 4:.

The teeth 81l are so arranged that as the sad iron supporting holder isrotated intermittently by its handle, the receiving portion for an ironis located in front of and in register with the opening of door 5. Theframe may thus be loaded with irons, and when sufficiently heated, a hotiron is taken off, a cold one put on, and the frame rotated onemovement. This brings the next hot iron into register with the dooropening, rotating the replaced cold iron beyond it, so that it is thusimpossible to take off a cold iron by mistake. The device may be usedcontinuously, always presenting a hot iron for removal, and will befound to thus insure uniformly heated irons, while greatly economizingthe heat.

It will be understood that the rotatable holder may be made to carry anynumber of irons, the number of locking teeth corresponding, and may beotherwise changed or varied in design or construction by the skilledmechanic within the scope of the following claims.

What I claim is I 1. In a heater for sad irons, the combination of afiat stationary apertured base having a central bearing for the ironholder, a coni-form casing extending upwardly from the base providedwith a lateral opening and a door therefor and a covering top having acentral stem bearing opening, a rotatable iron supporting frameconsisting of an upper integral portion having apertured iron supportingfaces and lugs and a central stem engaging said bearing opening in thecase, a separately attached rotatable base therefor having a centralunder hearing, an operating handle secured to said central stem, andco-actingratchet teeth on the stationary and rotatable base respectivelyfor arresting said rotatable base and its frame against reverse rotationand for holding it to present one of its faces opposite to the dooropening in the case, sub stantially as set forth.

2. In a heater for sad irons, the combination of a stationary baseconsisting of a central bearing portion having radial arms andintervening heat circulation spaces, one of said arms being widened toprovide a hand shield, a coni-form casing extending upwardly from thebase having a lateral opening above said hand shield, a door, and acovering top provided with a central stem bearing opening, a rotatableiron-supporting frame having a corresponding central pivoting bearingand upwardly and inwardly sloping centrally open faces having outwardlyextending pairs of supporting lugs for the irons and an upper centralstem extending through the top of the easing and provided with a turninghandle, and co-acting ratchet devices on the stationary base and thebase of the iron-supporting frame respectively for holding the frameagainst reverse movement, substantially as set forth.

In testimony whereof I afiiX my signature in presence of two witnesses.

LAIRD J. JACKSON.
